To all whom it may'concern:

Be it 'known that I, .TETsUs'Hmo NAKAMI- GAWA, a subjectl of the Emperorof Japan, residing at New York, in the county of New York new anduseful'ImproveInentsin Fly-Traps,

of which the following is a specification.

This invention relates to flyltraps and has Y for its primary object theprovision of a" revolving baiting andgoonducting element and a receivingreceptacle' associated there'- with and opening thereonto formed oftransparent material which is exposed at all times l office of a highlyefficient attracting-medium j serving' to induce'the? flies yor yinsectsto 're-Y beyond the extremities thereof.

LAnother object fof the invention isto provide a trap of- 4this characterwhich will 1n clude a revolving trapping elementw and' a receivingreceptacle, of transparent material and servingto per-y mit the light tobe projected Vinlthe direction of a transparenthood whichis partly dise'posed over the revolving element and means Y on the elementco-actingwith the hood to q form a guard to prevent accidental escape ofthe flies from betweenthe hood and saidelement during the catching andtrapping pef riods of itsk rotation, the said means being designed alsowith a view vof--fpreventing any material obstruction ofthe light raysat the stated point relatively of'the'revolving ele` ment at any timeduring the rotation of said element, or in other words, toprovidelcoacting elements of a trap in 1which light may besatisfactorily used as l abait and constantly exposed in the trappingpath of the 1. l A' UI!

and State of New York, have inventedv to thev reoeptacle'wherebythelatter being formed through forming a part of this Fig. 4 isa detailview of parts of the trap. As shown in Figs. l and 2 of the drawings,the hood, indicated' at 423,'is provided with an arcuate Vinlet section24. A roller 25 is jour-l naled inthe casing 28a below the arcuatesection 24 and is operatively connected inl any suitable manner with amotor indicated conventionally." The roller 25 is provided upon vits,peripheryy with 'several' rows of pins 27, the said rows beingspacedfrom each other. A roller 2 8.is journaled in the casi ing 1 and a belt29 is trained around the rollers 25 -and 28. The belt 29 is providedwith several rows of openings 30' adapted t'o rei ceive the pins 27 asthe saidl belt passes around the roller 25.v A ledgev 31 is mounted inthe casing'l -below the hood 23 and spaced from the same and the edgeportion of the said ledge 3() terminates in the vicinity ofthe path ofmovement ofthe pins 27 and* vthe said sectionl 24 and thev flies arecompelled to pass under the hood 23, Vhen they arrive under the hoodthey observe l beams of' light coming through the cage 4 from' theopening 3 in the panel` 2 and said transparent hood 24 and 'consetheflies ypass through thel run-ways 5 toward the openings 8 and arektrapped in the cage 4. The relatively of the and the openings uentlyinlet end of the hood 24Y 3 so that the'beams of light which enter thecage 4 will be projected as shown in the dotted lines in said llghtbeams will be also prea 'tangent to,l the roller 25. 'The obliquely,Fig.v l and sented at run-ways 'are disposed hoodv 24 is formed oftransparentvmaterialju and by projecting the Vlight the said rollerf25,it follows, that light which at a tangent tov emanates from the cage/Lwill be used tom v-Y'proper advantage' towardinviting4 the flies. 'Thepins 27 serve to permit free passage of light through said hood at alltimes and as a consequence thereof the main path of entrance to the cagewill be fully exhibited. In the form of the invention shown in Fig. 3 ofthe drawing, a polylateral roller 6 is journaled for rotation in thecasing 1 and is operated in any suitable manner byy a lnotor indicatedat 26 by the dotted lines in the said gure. Part of the roller is dis-1n a downward direction toward and under Y the hood 23. From under thehood 23 the flies pass through the run-ways 5 into the` ledge 31 is ofresilient material and bears hereinbefore referrechto operationof therevolving trapping element.
